Question

A car rental agency charges $75 per week plus $0.25 per mile to rent a car.a. write an equation that expresses the weekly cost to rent the car, y, in terms of the number of miles driven during the week, x.b. how many miles did you drive during the week if the weekly cost to rent the car was $ 100?

Answer 1

We will have the following:

a. The expression will be:

`y=0.25x+75`

b. We determine the miles driven as follows:

`\begin{gathered} 100=0.25x+75\Rightarrow0.25x=25 \\ \\ \Rightarrow x=100 \end{gathered}`

So, you drove 100 miles.
